How many liters of a 3 M NaOH stock solution would you need to make 552 mL of a 105 mM NaOH dilution
Ganezh [65]

Answer:

0.01932 L

Explanation:

First we <u>convert 105 mM to M</u>:

  • 105 mM / 1000 = 0.105 M

Next we <u>convert 552 mL to L</u>:

  • 552 mL / 1000 = 0.552 L

Then we use the following equation:

  • C₁V₁=C₂V₂

Where:

  • C₁ = 3 M
  • V₁ = ?
  • C₂ = 0.105 M
  • V₂ = 0.552 L

We<u> input the given data</u>:

  • 3 M * V₁ = 0.105 M * 0.552 L

And <u>solve for V₁</u>:

  • V₁ = 0.01932 L

C. Chemical energy. What is the difference in chemical energy between organic and inorganic
Olenka [21]
There are chief differences between organic and inorganic compounds. ... The main difference is in the presence of a carbon atom; organic compounds will contain a carbon atom (and often a hydrogen atom, to form hydrocarbons), while almost all inorganic compounds do not contain either of those two atoms.
